Rocket utilization

Ref 130, p 220) and by Great Britain (Vol 3, C498-R). These rockets utilized BlkPdr as proplnt, fuse (Ref 122) and as an expl. Up to the middle of the last century the history of pyrotechnics is the history of BlkPdr. Even now, as will be discussed in Section 7, large quantities of BlkPdr are used as an igniter. By the late 18 th century a new age in pyrotechnics commenced thru the synthesis of K chlorate (Vol 2, C190-R), the discovery of Fulminates (Vol 6, F216-R) and the identification of the minerals which would impart color to a flame. The discovery of electricity brought about pure chemicals and hence, better flame colors, new oxi-...

The most advanced among today s projects is the future American reusable launch system known as Venture Star. It utilizes two new concepts that are expected to boost efficiency and cut down the cost of a payload. The first is the single stage-to-orbit concept—the launch vehicle carries the entire propellant load and does not have any expendable parts. The latter is planned to be achieved by a revolutionary rocket engine design called Aerospike. The bell-shaped noz-... 

The utilization of combustible solid materials in propulsion devices is by no means a modern development. There is evidence that the first rockets were used in India around 2000 b.c., and the Chinese are known to have experimented with pellatized gun powder in rockets during the Tang dynasty... 

Moreover, novel applications of nuclear reactions involving technetium are being developed. Among them, multitracer utilization, molecular rocket reactions and shock wave enhancement phenomena are up-to-date examples. All these aspects are presented in this review paper.

In accordance with data of 2001, military chemical waste in Georgia consists of rocket fuel (about 1500 tonnes), napalm (912 tonnes), and large amount of chloropicrin. In spite of the fact that they are partially utilized, the rest poses still concern and requires great attention. 

Table 3.3 gives the total uses of hydrogen. Ammonia production is by far the most important application, followed by methanol manufacture. Hydrogenations in petroleum refineries are an important use. Many other industries utilize hydrogen. Miscellaneous uses include hydrogenation of fats and oils in the food industry, reduction of the oxides of metals to the free metals, pure hydrogen chloride manufacture, and liquid hydrogen as rocket fuel. 

Rocket Engine. A non-airbreathing reaction propulsion device that consists essentially of an injector, thrust chambers) and exhaust nozzle(s), and utilizes liquid fuels and oxidizers at controlled rates from which hot gases are generated by combustion and expanded thru a nozzle(s) (Ref 40a, p 125)... 

Products can be found in every principal market area including rocket motor and shell casings, air and gas pressure tanks, aircraft wing fuel tanks, utility poles, automotive and truck drive shafts, sailboat masts, vaulting poles, fishing rods, golf shafts, railroad tanks cars, and pipes and tanks for oil, gas, and chemical processing. 

The standard ASTM D2585 filament wound pressurized bottle test method utilizes a 0.15-m (5.75-in.)intemal diameter filament wound bottle as the test article. This standard test method (with variation in bottle sizes) has been used extensively by the rocket motor industry [47-50] to evaluate glass, aramid, and graphite fiber composite vessel performance. This test method has generally shown good results, but is a relatively expensive test method. Testing of one 0.5-m (20-in.) diameter bottle can cost up to 20K. Other disadvantages are ... 

Specific impulse, calculated by this technique, represents a 100% conversion of chemical energy to mechanical energy, and, therefore, is an upper limit to the performance available from a real rocket engine. However, regardless of the technique utilized, the theoretical Is of each of the systems are compared on a common basis (e.g.y at the same combustion chamber pressure, nozzle geometry, exit pressure, etc.) with the desired performance level dictated by the mission and engine system rquirements. 

In summary, all features of the liquid rocket engine combustion processes are extensively affected by injector design, and any simplified combustion model, in which the essential three-dimensional nature of the flow processes is ignored, can only be of qualitative significance. Nevertheless, these simplified models are useful in giving us some insight into the nature of the physicochemical phenomena that determine engine performance. In this connection, steady-state combustion rates and overall combustion efficiencies in propellant utilization are far less important practical problems than are control or elimination of instabilities, excessive heat transfer, and hard starts. 

The Germans used hydrogen peroxide of 80-85% concentration, alone or in mixtures with combustibles, as a fuel for the big V2 rockets during World War II. The utilization of hydrogen peroxide for rocket propulsion and the explosive properties of hydrogen peroxide and its mixtures will be discussed in later sections (pp. 299, 307).

Catalytic Ignition(Rocketry). A method of igniting the main propints in a rocket combustion chamber by utilizing a solid or a liq catalyst to initiate chem decompn or breakdown of one of the proplnts and thereby to generate ignition temp and pressure Ref Rocket Encycl(1959), 73... 

In order that a rocket may be launched on a definite trajectory, a device called a launcher is required. Aside from providing means for initiating ignition of the rocket propint, the launcher is required only to aim the rocket. Consequently, rocket launchers may be so light and portable that they are wheel-mounted or motorized, aircraft-mounted, or, in the case of the bazooka, designed to be carried about by a man. They utilize rails, posts, tubes, or other devices to both carry and guide the rocket. Thus, rockets can be fired from aircraft and from ground areas inaccessible to conventional artillery... 

The other two processes, by Rockwell/Cities Service and Bell Aerospace, are based on Rocket Tehcnology.
